IMPROVEMENT IN REVERSIBLE LVATCHES.

Specification forming part of Letters Patent No. 184,420, dated November14, 1876; application filed l October 21, 1876.

To all whom it 'may concern:

Be it known that I, MARTIN PADDEN, of Pittsburg, in the county ofAllegheny and State of Pennsylvania, have invented a new and usefulImprovementin Reversible Latches; and I do hereby declare the followingto be a full, clear, and exact description thereof, referenee being hadto the accompanying drawing, forming part of this specification, inWhich- Figure 1 is a plan view of the latch, the top plate beingremoved, showing the position of the different parts when in operation.Fig. 2 is a like view, showing the position of the parts of the latchwhen they are ready for reversal and Fig. 3 is a perspective view of theyoke and sliding stop.

Like letters of reference indicate like parts in each.

My invention relates to that classl of knoblatches usually known asreversible latches,7 where the position ofthe latch-bolt may be changed,so as to place the bevel to suit either a right or left hand door; auditconsists in combining with the slotted yoke a slide, held in place by,and working in,vthe slot of the yoke, said slide being provided with arecess to receive the head of the bolt, and being capable of sufcientmotion to allow the square portion of the bolt to be Withdrawn from thecase and be reversed.

To enable others skilled in the art to make and use my invention, I willdescribe its construction and operation.

The latch-case A is of the usual or any known construction, providedwith the hub a, working in the yoke B. The arms b b of the yoke B areattached together by the brace c, in which is cutthe recess d, toreceive the shank of the bolt. In the slot formed by the arms b b Iplace the slide E, capable of motion in the slot, said slide beingprovided With the recess e, for the reception of the head h of the boltH. The said bolt is of the usual construction in reversible latches,being provided with the cylindrical stem f back of the square portion,and the shank i, of less diameter, said shank terminating in the vheadh. The shank rests in the recess d of lthe brace c, and the head h inthe recess e of the slide. The spring s upon the shank i rests betweenthe brace c and slide E, holding the several parts in their relativepositions when the lock is in use. Attached to the slide E, andpassingunder the arm b, is the arm 1c, which extends beside the arm b tothe edge ofthe screw-hole l. The spring m, working against the yoke B,presses the latch forward in the usual manner.

When the latch is in use the several parts occupy the positions shown inFig. 1. When the latch-bolt is to be Withdrawn, the hub a is turned inthe yoke B, and the slide E, held against the end of the yoke by thespring s, withdraws the boltH. When the latch is to be reversed, thebolt H is drawn out of the case, the spring s being contracted, andpermitting the slide to move in the slot suciently to free the squareportion of the bolt from the case, when it can be reversed. When thelatch is being reversed, the slide-ar1n 7c, moving with the slide E,passes over the screw-hole l. After the latch is attached to the door,the attaching-screw, passing through said hole, prevents the advanceofthe slide, and at the same time precludes the possibility of thereversal of the latch. y What I claim as my invention, and desire tosecure by Letters Patent, is-

In areversible latch, the combination of the v slotted yoke, the slide,held in place by, and

Working in, the slot of the yoke, and theswivelng bolt, substantially asand for the purpose'specilied.

In testimony whereof I, the said MARTIN PADDEN, have hereunto set myhand.
